header("Location:...") much faster then http-equiv="refresh"? too fast?

Hi, I have a strange problem. I have a page that displays a list of records. When the user clicks on the delete link by one of the records, a php script is taking care to delete that specific record and then redirects back to the record list. I use PEAR::DB with MySQL. When I use header("Location: ...") to redirect the user back to the record list page, many times the screen still displays the old list and I have to refresh the page so see that the record was deleted. At first I thought that the page is redisplayed from the cache so I added the appropriate meta tags to make sure that the page will not be cached by the browser. Since sometimes it worked and sometimes it didn't, I started suspecting the the problem may be with the fact that the database (mysql) may have not removed the record yet by the time the record list is redisplayed. I decided to try to use the http-equiv="refresh" meta tag with a delay of 1 second, and suddenly the problem has disappeared. I also worked by setting the delay to 0. Does the above suspicion I have even make sense? Why would mysql not complete the delete when the delete is executed? Avi -- Avi Schwartz avi@CFFtechnologies.com "I have to share the credit.
